762aa86b - [AArch64] Canonicalize NVCAST to bitcast under LE (#223388)

[AArch64] Canonicalize NVCAST to bitcast under LE (#223388) A NVCAST is equivalent to a BITCAST under LE. This canonicalises the NVCAST to BITCAST under LE like we do for ARM, so there is only one representation, then fixes up the places that were assuming nvcast.
